1.3 Safety guide
Only qualified electricians are allowed to operate on the VFD.
Do not carry out any wiring, inspection or component replacement when
the power supply is applied. Ensure all input power supply is disconnected
before wiring and checking and always wait for at least the time designated
on the VFD or until the DC bus voltage is less than 36V. The table below
describes the waiting time:
VFD model
Minimum waiting time
1PH 230V
0.4kW–2.2kW
5 minutes
3PH 230V
0.4kW–7.5kW
5 minutes
3PH 400V
0.75kW–110kW
5 minutes
Do not refit the VFD unless authorized; otherwise, fire, electric shock or
other injury may occur.
The base of the radiator may become hot during running. Do not touch to
avoid hurt.
The electrical parts and components inside the VFD are electrostatic. Take
measurements to avoid electrostatic discharge during related operation.
1.3.1 Delivery and installation
Please install the VFD on fire-retardant material and keep the VFD away
from combustible materials.
Connect the optional brake parts (braking resistors, braking units or
feedback units) according to the wiring diagram.
Do not operate on the VFD if there is any damage or components loss to
the VFD.
Do not touch the VFD with wet items or body; otherwise, electric shock
may occur.
Note:
Select appropriate moving and installing tools to ensure a safe and normal running of the
VFD and avoid physical injury or death. For physical safety, the erector should take some
mechanical protective measurements, such as wearing exposure shoes and working
uniforms.

Goodrive20-EU Series VFD Safety precautions
-3-
Ensure to avoid physical shock or vibration during delivery and installation.
Do not carry the VFD by its cover. The cover may fall off.
Install away from children and other public places.
The leakage current of the VFD may be above 3.5mA during operation. Ground properly
and ensure the grounding resistor is less than 10Ω. The conductivity of PE grounding
conductor is the same as that of the phase conductor.
R, S and T are the input terminals of the power supply, while U, V and W are the motor
terminals. Please connect the input power cables and motor cables properly; otherwise, the
damage to the VFD may occur.
1.3.2 Commissioning and running
Disconnect all power supplies applied to the VFD before the terminal wiring
and wait for at least the designated time after disconnecting the power
supply.
High voltage is present inside the VFD during running. Do not carry out any
operation except for the keypad setting.
The VFD may start up by itself when P01.21=1. Do not get close to the VFD
and motor.
The VFD cannot be used as "Emergency-stop device".
The VFD cannot be used to brake the motor suddenly. A mechanical brake
device should be provided.
Note:
Do not switch on or off the input power supply of the VFD frequently.
For VFDs that have been stored for a long time, set the capacitance and carry out
inspection and pilot run on the VFD before use.
Close the front cover before running; otherwise, electric shock may occur.
1.3.3 Maintenance and component replacement
Only well-trained and qualified professionals are allowed to carry out
maintenance, inspection, and component replacement on the VFD.
Disconnect all the power sources applied to the VFD before terminal
wiring, and wait for at least the time designated on the VFD after
disconnecting the power sources.
Take measures to prevent screws, cables and other conductive matters
from falling into the VFD during maintenance and component
replacement.

Goodrive20-EU Series VFD Safety precautions
-4-
Note:
Select proper torque to tighten screws.
Keep the VFD and its parts and components away from combustible materials during
maintenance and component replacement.
Do not carry out insulation voltage-endurance test on the VFD, or measure the control
circuits of the VFD with megameters.
1.3.4 What to do after scrapping
The heavy metals inside the VFD should be treated as industrial effluent.
When the life cycle ends, the product should enter the recycling system.
Dispose of it separately at an appropriate collection point instead of
placing it in the normal waste stream.

reactor, braking unit, and braking resistor.
3. Whether the VFD is installed on non-flammable materials, and whether its heat-emitting
accessories (such as reactor and braking resistor) are kept away from inflammable
materials.
4. Whether all the control cables are wired separately from power cables, and whether
electromagnetic compatibility (EMC) specification requirements are taken into full
account during the wiring.
5. Whether all the grounding systems are properly grounded according to the
requirements of the VFD.
6. Whether all the installation spacings of the VFD meet the requirements stated in the
manual.

torque meets the requirements.
9. Whether screws, cables, or other conductive items drop into the VFD. If yes, take them
out.
2.1.5 Basic commissioning
Complete the basic commissioning as follows before using the VFD.
1. Perform autotuning if required. Remove the motor load, if possible, to perform dynamic
parameter autotuning; and if the load cannot be removed, you can perform static
autotuning.
2. Adjust the ACC/DEC time according to the actual operation conditions of the load.

Chapter 3 Installation guidelines
The chapter describes the mechanical installation and electric installation of the VFD.
Only qualified electricians are allowed to carry out what described in this
chapter. Please operate as the instructions in Chapter 1 "Safety
precautions". Ignoring these may cause physical injury or death or
damage to the devices.
Ensure the power supply of the VFD is disconnected during the operation.
Wait for at least the time designated after the disconnection if the power
supply is applied.
The installation and design of the VFD should be complied with the
requirement of the local laws and regulations in the installation site. If the
installation infringes the requirement, our company will exempt from any
responsibility. Additionally, if users do not comply with the suggestion,
some damage beyond the assured maintenance range may occur.
3.1 Mechanical installation
3.1.1 Installation environment
The installation environment is the safeguard for a full performance and long-term stable
functions of the VFD. Check the installation environment as follows:
Environment
Conditions
Installation
site
Indoor
Environment
temperature
-10°C to +50°C, and the temperature changing rate is less than
0.5°C/minute.
If the ambient temperature of the VFD is above 40°C, derate 1% for every
additional 1°C.
It is not recommended to use the VFD if the ambient temperature is above
50°C.
In order to improve the reliability of the device, do not use the VFD if the
ambient temperature changes frequently.
Please provide cooling fan or air conditioner to control the internal ambient
temperature below the required one if the VFD is used in a closed space
such as in the control cabinet.
When the temperature is too low, if the VFD needs to restart to run after a
long stop, it is necessary to provide an external heating device to increase
the internal temperature; otherwise, damage to the devices may occur.
Humidity
RH ≤90%.
No condensation is allowed.

Running
environment
condition
The installation site of the VFD should fulfill the following requirements.
Away from electromagnetic radiation sources.
Away from oil mist, corrosive gases and combustible gases.
Ensure foreign object like metal powder, dust, oil and water will not fall into
the VFD (do not install the VFD onto combustible object like wood).
Away from radioactive substance and combustible objects.
Away from harmful gases and liquids.
Low salt content.
No direct sunlight.
Altitude
Below 1000m.
When the altitude exceeds 3000m, consult the local INVT dealer or office
for details.
When the altitude exceeds 1000m, derate by 1% for every increase of
100m.
Vibration
Max. vibration acceleration: 5.8m/s2 (0.6g)
Installation
direction
The VFD should be installed on an upright position to ensure sufficient cooling
effect.
Note:
Goodrive20-EU series VFDs should be installed in a clean and ventilated environment
according to enclosure classification.
Cooling air must be clean, free from corrosive materials and electrically conductive dust.
3.1.2 Installation direction
The VFD may be installed in a cabinet.
The VFD needs be installed in the vertical position. Check the installation site according to the
requirements below. Refer to Appendix B "Dimension drawings" for details.
3.1.3 Installation mode
a) Wall and rail mounting for the VFDs (single phase 230V/three phase 400V, ≤2.2KW and
three phase 230V, ≤0.75KW)
